The Bouguer anomaly is first transformed by linear filtering into density variations located between two planes 1100 and 2500 m deep. These densities are then transformed into thicknesses with a constant density contrast of 0.4 g/cm3 with two geological constraints for the second and third interface: —minimum at 2500 m depth; —maximum below a variable limit given by geology. This gives the contact between the second and third layer. Differences between measured and computed gravity are then applied by a similar procedure to a layer located between depths of 0 and 500 m, giving the contact between the first and second layer. Interesting secondary anticlines and transverse faults are shown by various structural maps. %U https://www.earthdoc.org/content/journals/10.1111/j.1365-2478.1983.tb01075.x
